So how many strings do you tighten? First, let them all tighten to the point where they make a clear voice, or even tighter than that. Once the strings make a clear sound. Use a convenient Playboy tuner to tighten each string to the pitch.
Wow! How fierce you are, you are done! But not completely. these are brand new steel guitar strings that have never been placed in this tension before life. They need to stretch out! You can help rework your guitar by pulling up the 12th string and the strings of each string and repeat the process until it looks like the strings are consistent.
